Paul J. Chang, MD, medical director of enterprise imaging at the University of Chicago, began his presentation Monday morning at RSNA 2016 by saying his goal was to upset “everyone in the room” with his opinions on quality and IT. He said this with a smile, of course, but he did go on to speak about quality in different terms than radiologists are used to hearing.

Dosimetry using average-sized phantoms leads to considerable errors

The use of non-size-dependent reference phantoms to calculate CT dose can lead to errors in calculating the radiation received by a patient, according to an article published in the American Journal of Roentgenology. Using data from the National Lung Screening Trial, researchers found using an average height and weight to calculate dose can lead to errors of up to 200 percent when compared with a more accurate estimate using a particular patient’s height and weight.
